Frequent Mouth Ulcers: Causes, Concerns, and When to See a Doctor - Dentistry

Mouth ulcer?


Hello, doctor.
I don't smoke, drink alcohol, or chew betel nut, but I frequently get mouth ulcers.
They usually take 7 to 14 days to heal, and sometimes I get two ulcers at once.
The most severe case was when two ulcers appeared a week after the previous ones healed, and they are always in different locations.
Is this normal? Should I see a doctor? Is there a possibility that this could be oral cancer? I drink plenty of water and usually sleep from around 1 AM to 10 AM, but sometimes I wake up to use the bathroom twice.
With this ongoing issue of mouth ulcers, is there anything I should be particularly aware of?

Hello: It is recommended to have a blood test to check the immune function values to confirm whether there are any immune disorders or autoimmune diseases.

More Info


Frequent mouth ulcers, also known as aphthous ulcers, can be a frustrating and painful condition. Your description of experiencing ulcers that take 7 to 14 days to heal, with new ones appearing shortly after the old ones heal, suggests a recurring issue that may require further investigation. While it is not uncommon for individuals to experience occasional mouth ulcers, the frequency and persistence you describe warrant a closer look.


Possible Causes of Frequent Mouth Ulcers
1. Stress and Anxiety: Emotional stress is a well-documented trigger for mouth ulcers. If you are experiencing significant stress, this could be contributing to the frequency of your ulcers.

2. Nutritional Deficiencies: Deficiencies in certain vitamins and minerals, particularly vitamin B12, folic acid, iron, and zinc, can lead to the development of mouth ulcers. A balanced diet is crucial for maintaining oral health.

3. Hormonal Changes: Hormonal fluctuations, particularly in women, can lead to increased occurrences of mouth ulcers. This is often seen in relation to menstrual cycles.

4. Food Sensitivities: Certain foods, such as citrus fruits, chocolate, coffee, and spicy foods, can trigger or exacerbate mouth ulcers in some individuals.

5. Underlying Health Conditions: Conditions such as celiac disease, inflammatory bowel disease (IBD), and autoimmune disorders can manifest with recurrent mouth ulcers. If you have other symptoms, such as gastrointestinal issues or skin problems, it may be worth discussing these with your doctor.

6. Oral Hygiene Products: Some toothpaste and mouthwashes contain sodium lauryl sulfate (SLS), which can irritate the oral mucosa and lead to ulcers in susceptible individuals.


Concerns Regarding Oral Cancer
While the presence of recurrent mouth ulcers can be concerning, especially if they are persistent or accompanied by other symptoms (such as difficulty swallowing, unexplained weight loss, or changes in voice), it is important to note that most mouth ulcers are benign and not indicative of oral cancer. Oral cancer typically presents with other symptoms, such as lumps, persistent sores that do not heal, or changes in the lining of the mouth.


When to See a Doctor
You should consider seeing a healthcare professional if:
- Your mouth ulcers persist for more than two weeks without healing.

- You experience significant pain or discomfort that interferes with eating or drinking.

- You notice any unusual changes in the appearance of the ulcers, such as a hard border or a lump.

- You have other symptoms, such as fever, swollen lymph nodes, or unexplained weight loss.


Recommendations
1. Dietary Adjustments: Consider keeping a food diary to identify any potential triggers. Ensure you are getting adequate vitamins and minerals.

2. Stress Management: Engage in stress-reducing activities such as yoga, meditation, or regular exercise.

3. Oral Hygiene: Maintain good oral hygiene, but consider switching to SLS-free toothpaste if you suspect it may be irritating your mouth.

4. Hydration: Continue to drink plenty of water, as hydration is essential for overall health and can help maintain the moisture of oral tissues.

5. Consultation: If the ulcers continue to be a problem, consult with a dentist or an oral specialist who can provide a thorough examination and possibly recommend treatments or further investigations.

In summary, while frequent mouth ulcers can be distressing, they are often manageable with lifestyle changes and proper care. However, persistent or severe cases should be evaluated by a healthcare professional to rule out any underlying conditions.
